From: Oliver Upton Date: Wed, 20 Jul 2022 09:22:47 +0000 (+0000) Subject: KVM: Shove vm stats_id init into kvm_create_vm() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f2759c08d8f4d584e88d129e7392260fb4079ec2;p=linux.git KVM: Shove vm stats_id init into kvm_create_vm() Initialize stats_id alongside other struct kvm fields to make it more difficult to unintentionally access stats_id before it's set. While at it, move the format string to the first line of the call and fix the indentation of the second line. No functional change intended.
